[PATCH AUTOSEL 4.19 21/26] HID: chicony: add another quirk for PixArt mouse

[Sasha Levin]

From: Oleksandr Natalenko <oleksandr@redhat.com>

[ Upstream commit dcf768b0ac868630e7bdb6f2f1c9fe72788012fa ]

I've spotted another Chicony PixArt mouse in the wild, which requires
HID_QUIRK_ALWAYS_POLL quirk, otherwise it disconnects each minute.

USB ID of this device is 0x04f2:0x0939.

We've introduced quirks like this for other models before, so lets add
this mouse too.

[Sasha Levin]

There's a new ALPS touchpad/pointstick combo device that requires
MT_CLS_WIN_8_DUAL to make its pointsitck work as a mouse.
